Journal ArticleDOI
Loss of function of a rice brassinosteroid insensitive1 homolog prevents internode elongation and bending of the lamina joint.
Chizuko Yamamuro,Yoshihisa Ihara,Xiong Wu,Takahiro Noguchi,Shozo Fujioka,Suguru Takatsuto,Motoyuki Ashikari,Hidemi Kitano,Makoto Matsuoka +8 more
TL;DR: The phenotypical and molecular characterization of a rice dwarf mutant, d61, that is less sensitive to BR compared to the wild type is reported, and introduction of the entire OsBRI1 coding region into d61 plants complemented the mutation to display the wild-type phenotype.
Journal ArticleDOI
Erect leaves caused by brassinosteroid deficiency increase biomass production and grain yield in rice.
Tomoaki Sakamoto,Yoichi Morinaka,Toshiyuki Ohnishi,Hidehiko Sunohara,Shozo Fujioka,Miyako Ueguchi-Tanaka,Masaharu Mizutani,Kanzo Sakata,Suguru Takatsuto,Shigeo Yoshida,Hiroshi Tanaka,Hidemi Kitano,Makoto Matsuoka +12 more
TL;DR: It is shown that the erect leaf phenotype of a rice brassinosteroid–deficient mutant, osdwarf4-1, is associated with enhanced grain yields under conditions of dense planting, even without extra fertilizer, suggesting that regulated genetic modulation of brassinosterone biosynthesis can improve crops without the negative environmental effects of fertilizers.
Journal ArticleDOI
Brassinosteroid functions in a broad range of disease resistance in tobacco and rice.
Hideo Nakashita,Michiko Yasuda,Takako Nitta,Tadao Asami,Shozo Fujioka,Yuko Arai,Katsuhiko Sekimata,Suguru Takatsuto,Isamu Yamaguchi,Shigeo Yoshida +9 more
TL;DR: Analysis of data suggests that steroid hormone-mediated disease resistance (BDR) plays part in defense response in tobacco and functions in the innate immunity system of higher plants including dicotyledonous and monocotylingonous species.
Journal ArticleDOI
The AtGenExpress hormone and chemical treatment data set: experimental design, data evaluation, model data analysis and data access.
Hideki Goda,Eriko Sasaki,Kenji Akiyama,Akiko Maruyama-Nakashita,Kazumi Nakabayashi,Weiqiang Li,Mikihiro Ogawa,Yukika Yamauchi,Jeremy Preston,Ko Aoki,Takatoshi Kiba,Suguru Takatsuto,Shozo Fujioka,Tadao Asami,Takeshi Nakano,Hisashi Kato,Takeshi Mizuno,Hitoshi Sakakibara,Shinjiro Yamaguchi,Eiji Nambara,Yuji Kamiya,Hideki Takahashi,Masami Yokota Hirai,Tetsuya Sakurai,Kazuo Shinozaki,Kazuki Saito,Shigeo Yoshida,Yukihisa Shimada +27 more
TL;DR: Genome-wide transcriptional gene-to-gene correlations, analyzed by hierarchical cluster analysis (HCA), indicated that the data set is useful for identification of clusters of co-expressed genes, and to predict the functions of unknown genes, even if a gene's function is not directly related to the experiments included in AtGenExpress.
Journal ArticleDOI
A Rice Brassinosteroid-Deficient Mutant, ebisu dwarf (d2), Is Caused by a Loss of Function of a New Member of Cytochrome P450
Zhi Hong,Miyako Ueguchi-Tanaka,Kazuto Umemura,Sakurako Uozu,Shozo Fujioka,Suguru Takatsuto,Shigeo Yoshida,Motoyuki Ashikari,Hidemi Kitano,Makoto Matsuoka +9 more
TL;DR: It is concluded that D2/CYP90D2 catalyzes the steps from 6-deoxoteasterone to 3-dehydro-6- deoxoteastersone and from teasteroneto 3- dehydroteasterone in the late BR biosynthesis pathway.
